STM32-H107 Board overheating

[jaka]

Hi

I'm using Olimex STM32-H107 board with STM32F107 microprocessor on it. The board is powered with 5 V through the both EXT1-40 and EXT2-40 pins. For some unknown reason gets the microprocessor after few seconds very hot and I need to disconnect the power supply.

Does anybody have a clue why this is happening?

Thank you for any help.

Regards
